This installation manual is applicable for all pv system of 500 m or more away
from the coastline. If your system gets closer please contact Suntech's Global Quality
& Customer Support department or our regional representatives and/or refer to the
Near-coast Installation Guide for Suntech Power Photovoltaic Module.
•
Do not use modules near equipment or in locations where flammable gases may
be generated or collected.
General Installation
•
The module mounting structure must be made of durable, corrosion-resistant and
UV-resistant material.
•
In regions with heavy snowfall in winter, select the height of the mounting system
so that the lowest edge of the module is not covered by snow for any length of time. In
addition, ensure that the lowest portion of the module is placed high enough so that it
is not shaded by plants, trees or damaged by ground soil moved by or through the air.
•
For ground mounting systems, the minimum distance Suntech recommend from
the ground to the bottom of the module is at least 24 inches (60cm).
•
Modules must be securely attached to the mounting structure. For Clamping
System installation methods, the recommended maximum compression for each clamp
is 2900 PSI (20 Mpa) in order to avoid potential damages to module frames.
•
Provide adequate ventilation under the modules in conformity to your local
regulations. A minimum distance of 10 cm between the roof plane and the frame of the
module is generally recommended.
•
Always observe the instructions and safety precautions included with the module
support frames.
•
Before installing modules on a roof, always ensure the roof construction is suitable.
In addition, any roof penetration required to mount the module must be properly
sealed to prevent leaks.
•
Dust building up on the surface of the module can impair with the module
performance. Suntech recommends installing the modules with a tilt angle of at least
10 degrees, making it easier for dust to be removed by rain.
•
Observe the linear thermal expansion of the module frames (the recommended
minimum distance between two modules is 2 cm).
•
Always keep the backsheet of the panel free from foreign objects, plants and
vegetation, structural elements, which could come into contact with the panel,
especially when the panel is under mechanical load.
•
When installing a module on a pole, select a pole and module mounting structure
that will withstand the anticipated winds for the area.
•
Ensure panels are not subject to wind or snow loads exceeding the maximum
permissible loads, and are not subject to excessive forces due to the thermal expansion
of the support structures: Refer to the following installation methods for more detailed
information.

Mechanical Installation
Installation methods
•
Modules can be installed on the frame using mounting holes, clamps* or an
insertion system. Modules must be installed according to the following examples. Not
mounting the modules according to these instructions may void the warranty.
Module installed
with mounting holes
Module installed
with clamps
* The minimum recommended length for each clamp is 50 mm.
•
Module can be installed in both landscape and portrait modes.
•
The modules must be properly secured to their support so that they can withstand
live load conditions, including wind uplift, to the pressure they have been certified for.
It is the installer's responsibility to ensure that the clamps used to secure the modules
are strong enough.
Attachment guidelines
•
Select the proper installation method depending on the load(See below for more
detailed information).
•
With different installation methods, the modules have been tested to withstand
the loads of 2400 Pa, 3800 Pa and 5400 Pa according to IEC 61215 standard, equivalent
of 1600 Pa, 2500 Pa and 3600 Pa respectively under UL 1703 standard.
•
The diagrams in the tables below are designed for illustration purpose. For each
installation, modules can be installed either in portrait or landscape mode.
